Abstract
It is presented a method for controlling access to an access object. The method is performed in an access control device and comprises the steps of: receiving a user input to reset the access control device; generating a new identifier for the access control device, and discarding any previously used identifier for the access control device; communicating with an electronic key to obtain an identity of the electronic key; obtaining a plurality of delegations, wherein each delegation is a delegation from a delegator to a receiver; and granting access to the access object only when the plurality of delegations comprise a sequence of delegations covering a delegation path from the access control device, identified using the new identifier, to the electronic key such that, in the sequence of delegations, the delegator of the first delegation is the access control device, and the receiver of the last delegation is the electronic key.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
